It was one of the criticisms made from the very beginning of the project to pacify Barcelona's Consell de Cent street: gentrification. That is, the prices of apartments and commercial premises would rise, driving out longtime residents. Now, the study Price de la green: the rental market effects of Barcelona's green axes policy, Prepared by Pompeu Fabra University (UPF) professors Josep Maria Raya and Ghizlen Ouasbaa and Erasmus University Rotterdam professor Pedro de Solà-Morales Casals, it provides data on rental prices. In the areas closest to the green axis, rents rose between 12 and 14% more than in the rest of the city. The study confirms that rents are now around €200 more expensive than before, and has demonstrated this by comparing prices in the area at different distances from the green axis with those of other areas of the city over the last seven years. As expected, this increase has occurred mainly since the completion of the works, that is, in 2023, and it is foreseeable that, given the successful use of space by citizens and the calming of noise and traffic, it will increase even further in the future.
